European Ash Trees Likely To Go Extinct

" Europe could be about to lose all your ash trees, as plants are being affected by the disease on two different fronts. While the fungus that causes dieback of deadly ash has already made its way through much of the continent, including the crossing in the UK in 2012, a new threat has come in the form of EAB a invasive beetle has spread from Asia. In the largest study of ash, researchers have reached the grim conclusion that their chances of survival are not great.
The species is widespread, found in much of Europe, from Spain, in western Russia in the east, and is a common feature not only in deciduous forests, but also in many cities. However, since 1992, European trees have been suffering from dieback of ash, also known as Chalara, which is caused by Hymenoscyphus fraxineus fungus . From the tips of the leaves, the fungus causes darken and die, it extends to the branches, trunk, and eventually kills the entire tree. The fungus and is believed to affect more than 2 million square kilometers (770,000 square miles) of forest. The fungus has caused widespread declines ash across Europe, although not all trees succumb, and while some suggest that between 15 and 20 percent do not die, others predict that could kill nearly 95 percent of all ash trees in the UK alone. But those trees pulling through are now at risk of being hit again by the appearance of the boring beetles, and researchers simply do not believe that species can survive a second round. Beetles themselves do not cause damage to the tree, but its larvae bore under the bark and wood, eventually killing him. ash dieback has spread across Europe, killing many trees and even entire forests, as seen here. Debs eye / Flickr CC BY-NC-ND 2.0 "Among dieback fungus ash disease and a bright green beetle called the emerald ash borer, is likely to almost all ash trees in Europe will be eliminated - like the elm was largely eliminated by the Dutch elm disease, "said Dr. Peter Thomas, who co-authored the article published in the journal of Ecology. While France lost more than 90 percent of their elms from Dutch elm disease, which also came from Asia as the borer beetle, it is estimated that in the UK more than 25 million elms died. The removal of ash trees would be catastrophic not only for the species itself, but also the hundreds of creatures that depend on them. More than 1,000 have so far been associated with ash, including 12 species of birds, 55 mammals, and 239 insects. "Of these, more than one hundred species of lichens, fungi and insects depend on the ash tree and is likely to decline or become extinct if the ash was gone," says Dr. Thomas. "If the ash was the British countryside will never be the same again."
